首先：RStudio 是一个 IDE（集成开发环境）。您可能想使用 R（RStudio 使用的语言/统计程序，但也可以独立使用）。

您的问题非常不清楚，但如果（我不确定）您正在寻找一种在回归模型中使用虚拟变量的方法，您可能会考虑使用因子变量：

JOB <- factor(sample(1:3, 10, replace = TRUE), 
              levels= 0:3,
              labels = c("unemployed/ unskilled - non-resident",
                         "unskilled - resident",
                         "skilled employee / official",
                         "management/ self-employed/highly qualified employee/ officer"),
              ordered = TRUE
)

威奇会给你：

 [1] unskilled - resident                                        
 [2] unskilled - resident                                        
 [3] skilled employee / official                                 
 [4] skilled employee / official                                 
 [5] skilled employee / official                                 
 [6] unskilled - resident                                        
 [7] management/ self-employed/highly qualified employee/ officer
 [8] unskilled - resident                                        
 [9] skilled employee / official                                 
[10] management/ self-employed/highly qualified employee/ officer
4 Levels: unemployed/ unskilled - non-resident < unskilled - resident < ... < management/ self-employed/highly qualified employee/ officer

和历史类似。
